CF-5200 Frequently Asked Questions
Question number FAQ-0333
In a shock test using two Accelerometer, (1) how do you determine the transfer functions α1/α0, V1/V0, X1/X0: α = acceleration, V = velocity, X = displacement? (2) Will all of these yield the same value?
(1) When α0 is input to channel A and α1 to channel B, the frequency response function is measured to be α1 / α0.
(2) Although the physical meaning is different, the result is the same.
V1／V0＝α1×（1／Jω）÷{α0×（1／Jω）}＝α1／α0
X1／X0＝V1×（1／Jω）÷{V0×（1／Jω）}＝V1／V0
